telescopic engagement therewith and in such manner that the nut threadscarried by said nipple will be tightly embedded into the spindle or boltthreads thereunder, resulting in a frictional grip between the threadedmembers, which grip will be of sufficient tenacity to prevent the nutfrom loosening under vibration or through other causes, it beingunderstood that the said nut can be run oil by the application of awrench with out marring the threads.

It is also-obvious that the choke bore-engagement between the nipple andnut will not have any appreciable tendency to expand the washer due tothe fact that the cross-sectional area of said nut in the line ofresistance is much greater than the corresponding area of the nipple.Hence as the nipple is forced through the tapered bore of the Washer, awedging action takes place, whereby the outer straight face of saidnipple will change its shape slightly to somewhat taper form,approximately corresponding to the tapered bore of the washer, wherebythe pressure between the threads of the memberswill be gradual'from theouter end of the 111' pic, the said pressure decreasing in a directiontoward the nut body. 1

I claim:

In a nut-lock a nut body having a thin uninterrupted circular nippleextending 'Zrom its base, the some being uniform in (11- irmeterthroughout its l'ength; in combination with an engaging washer for thenipple the interior face of which is tapered with respect to thestraight outer face'of the continuous circular nipple, whereby the outerend only of said nipple is engaged by the washer to progressivelycompress the nipple into tapered form as it travelsto its seat thereinwhereby the disturbance of the molecules of the nipple caused throughits change of form will be gradual from the engaged end to the basethereof to thus prevent undue crystallization at any point.

In testimony that I claim the foregoing I have hereunto set my hand'atMilwaukee in the county of Milwaukee and State of Wisconsin in thepresence of two witnesses.
